摘要：Ba cteriological analyse s of 19 water sources around Lake Monoun and 17 around Lake Nyos were done in 2013 . That is, they de a lt with water used by the populations living in the vicinities of both lakes . Specifically survivors of Lake Nyos past CO 2 disaster ( gas explosion in 1986 that claimed about 1800 lives ) and the fast growing population inhabiting the vicinities of Lake Monoun. Water samples from wells, springs, and streams for multipurpose daily use were analysed for total coliforms, faecal coliforms and faecal streptococci using t he membrane filtration technique . Results revealed the presence of the three bacterial indicators in nearly all the water sources . In the Lake Monoun area, all the 19 analysed samples contained total coliforms, 16 (84.2%) and 17 (89.5 %) samples contained faecal coliforms and faecal streptococci, respectively. All the 17 samp les collected around Lake Nyos contained total a nd faecal coliforms, and 16 (94. 1%) samples contained faecal streptococci. Such high percentages of contamination rais e a concern on the suitability of th e water sources that are used for drinking and other d omestic purposes. The data provide evidence of fecal contamination in most of the water sources in both areas, implying health threat to consumers . There is a need to improve water sanitation in both areas
